c# - Cómo deserializar XML utilizando DataContractSerializer
asp.net .net (1)
Estoy tratando de deserializar un documento xml:
<?xml version="1.0"?>
<games xmlns = "http://serialize">
<game>
<name>TEST1</name>
<code>TESTGAME1</code>
<ugn>1111111</ugn>
<bets>
<bet>5,00</bet>
</bets>
</game>
<game>
<name>TEST2</name>
<code>TESTGAME2</code>
<ugn>222222</ugn>
<bets>
<bet>0,30</bet>
<bet>0,90</bet>
</bets>
</game>
</games>
clase .cs:
namespace XmlParse
{
using System.Collections.Generic;
using System.Runtime.Serialization;
[DataContract(Namespace = "http://serialize")]
public class game
{
#region Public Properties
[DataMember]
public string name { get; set; }
[DataMember]
public string code { get; set; }
[DataMember]
public long ugn { get; set; }
[DataMember]
public List<decimal> bets { get; set; }
#endregion
}
[KnownType(typeof(game))]
[DataContract(Namespace = "http://serialize")]
public class games
{
#region Public Properties
[DataMember]
public List<game> game { get; set; }
#endregion
}
}
Principal:
FileStream fs = new FileStream(Path.Combine(this.path, xmlDocumentName), FileMode.Open);
XmlDictionaryReader reader = XmlDictionaryReader.CreateTextReader(fs, new XmlDictionaryReaderQuotas());
DataContractSerializer ser = new DataContractSerializer(typeof(games));
// Deserialize the data and read it from the instance.
games deserializedPerson = (games)ser.ReadObject(reader, true);
reader.Close();
fs.Close();
DeserializedPerson muestra count = 0
¿lo que da?
Me lo imaginé. Quizás haya otras implementaciones pero esto funciona. Por mi vida, no pude encontrar ningún ejemplo que use Lista dentro de un objeto. Aquí hay un ejemplo de trabajo:

Leer y analizar el documento XML:
string fileName = Path.Combine(this.path, "Document.xml");
DataContractSerializer dcs = new DataContractSerializer(typeof(Games));
FileStream fs = new FileStream(fileName, FileMode.Open);
XmlDictionaryReader reader = XmlDictionaryReader.CreateTextReader(fs, new XmlDictionaryReaderQuotas());
Games games = (Games)dcs.ReadObject(reader);
reader.Close();
fs.Close();
